Well, what can be said about a one-page document? It's short and to the point.
120 Modern Bag Contents is exactly what it says on the wrapper. It's a bunch of generic items to allow a GM to randomly figure out what is in the bag that the group just decided to steal/loot off of... Whomever. (And GMs have all been there.).
I also got it for a Post-Apocalyptic RPG to add some flavour to the game, without introducing overpowered items. Usually, however, I'd want to pre-make found caches like this, but it will come in handy for just the random finds through rolling to find something, anything, to trade.
For modern games, well, you just found out what was in some poor person's bag that was just taken rudely away from them.
